Copper and tin make an amazing material called bronze ,,add chrome ,molybdenum or a number of elements to steel and you create steel alloys that resist mans attempts to destroy it ,aluminium is the same.

Unfortunately blueberry's and mushrooms are about as good as they get in their natural as delivered state , $100 worth of each will have you turning blue or brown if eaten at once,and probably make you exceptionally regular or irregular ! ,,maybe that is the aim!![thoughts of Willi Wonka here]
I know of no alloy of vegetable or fruit that does anything different than what it started out to be, as far as benefit goes.

Buy some nice parts ,,you could even get some you don't need!! , that if it was me would make me feel better .
